Variable Pitch Technology
Globally 99% of MultiRotors are manufactured with a Fixed Pitch Rotor System. It’s simple to fly and relatively cheap ( it does not need any high-end engineering ).
The Variable Pitch Rotor system is mainly used to manufacture Helicopters. It’s more complicated to operate, some parts are more expensive and it needs highly educated engineers and periodical maintenance.
So manufacturing a MultiRotor with a variable pitch system is very challenging but once succeeded there are many advantages and to name a few:
1) Rapid thrust changes allow for fast evasive maneuvers.
2) Quick thrust reversal and vertical descent.
3) Heavy payload capability.
4) Better stability in harsh conditions / high winds.
5) Longer endurance in cruise.
Range Rotor Performance
The Range Rotor FMR-4 is the ultimate aerial cargo and payload carrier. Two fuel powered engines and a variable pitch rotor system are unique features and have never been combined in a Multirotor before. Compared to other heavy-lift multirotors in the market the technology and performance of the FMR-4 is astonishing!

Payload Integration
The payload / gimbal applications are supplied by third parties but can be integrated with the Range Rotor MultiCopters.
Industrial
Lidar Sensors
EO IR Sensors
Hyper and Multispectral Sensors
Homeland Security / Defence
Laser Designator, Laser Rangefinder, Laser Dazzler, IMSI Catcher, Counter UAS Dazzler / Aerial Private Cell Network.
Search / Rescue / Counter
Gremsy gimbal and IMSI Catcher and dual EO/R sensors with two antenna transmitter/receiver units for MultiCopters. Acts as a cellular tower and can detect, locate or identify the registered owners of active SIM cards / Mobile phones. For aerial search, rescue and disaster management.
Detect and Counter with aerial Laser Power
Gremsy Gimbal with a choice of 1W or 5W Laser Dazzler (532nm green-2km range) supported by a Laser Rangefinder, a Laser Designator and EO/IR camera’s for flight and targeting. While the 1W is mainly for dazzling the 5W could be highly effective to counter FPV drones by targeting the CMOS sensors and wash-out or burn the sensors and electronics .
About us
For over 10 years we had offices and facilities in Amsterdam, Pretoria and Dubai manufacturing X8 coaxial electrical MultiCopters and Payloads for industrial and defence related entities in the MEA region.
After the COVID period we moved all commercial activities to Amsterdam while developing the new technology Range Rotor FMR-4 and introducing the EMR-2 Tandem Copter on the European market.
